"I just love music and love the people in it. I mean, I love doing it. It's not stressful. It's a natural thing to me, you know," Berger said.

Fifty years ago, Berger, then a cabinet-maker, landed a coveted job at guitar maker C.F. Martin and Company in his native Nazareth, Penn. Martin guitars are now and were then arguably the best acoustic guitars in the world.

It turns out Berger was very good at fixing and building guitars.

In 1972, poor health forced him to leave Martin for Florida, where he found a climate good for his lungs and for building and selling his own high-end guitars, which he has done ever since.

Ogden: "I'm sure you have after you have either built or worked on a guitar, heard that guitar in performance or on record."

Berger: "Oh yeah."

Ogden: And what's that feeling like"

Berger: "Oh, I love it. I love it."

So not only is he a master builder, he uses master builder-level materials. Now, this might not mean anything to you. This is Brazilian Rosewood. It's might as well be unicorn horns for as difficult as it is to get.

If unicorn horns made the most beautiful-sounding guitars in the world. This stuff is more or less illegal to buy or sell because of different UN treaties. But, this is the holy grail right here."

Berger's wood FYI was obtained legally before the ban.

"See how it resonates? Voice of the braces," Berger said.

In his 50th year as a luthier, he still puts in at least 40 hours a week in his living room workshop, building 10 to 12 Berger guitars a year for rock luminaries like the guys in Aerosmith and the Eagles and serious amateurs on the First Coast and beyond.
